Support loading config via env var

Browse source 
In addition to loading the config via a `config.json` file, this change allows it to be loaded via an environment variable called `CZDS_CONFIG`. This makes it straightforward to deploy to services like Heroku, which tend to use env vars for config. See https://12factor.net/ for details.
